如何使用 ,而不出现连接错误 [复制链接]

小弟在用pb5写一个简单的流接口驱动，使用了ceddk库函数MmMapIoSpace。可是在编译时出现连接错误.
在下刚学写这样的驱动程序，还望大哥大姐们赐教！

DWORD DEM_Init( LPCTSTR pContext, LPCVOID lpvBusContext)
{
        OutputDebugString(L"MyDriver - DEM_Init - Context: ");
        OutputDebugString(pContext);
        OutputDebugString(L"\n");
       
        OutputDebugString(L"MyDriver - ~ DEM_Init\n");
        ELECTROMOTOR_GPACON=(ULONG)MmMapIoSpace(GPACON,4,FALSE);
        ELECTROMOTOR_GPADATA=(ULONG)MmMapIoSpace(GPADATA,4,FALSE);
        ELECTROMOTOR_1=(ULONG)MmMapIoSpace(EMOTOR_1,8,FALSE);

        return 0x1234;
}
错误内容：
LEDDRIVER.obj : error LNK2019: unresolved external symbol MmMapIoSpace referenced in function "unsigned long __cdecl DEM_Init(unsigned short const *,void const *)" (?DEM_Init@@YAKPBGPBX@Z)
BUILD: [01:0000000065:ERRORE] obj\ARMV4I\retail\LEDDRIVER.dll : fatal error LNK1120: 1 unresolved externals

简单啊，把它的实现包进来就不会出现错误 ^_^

请在source文件里链接ceddk.lib
例子如下：
TARGETLIBS= \
        $(_COMMONSDKROOT)\lib\$(_CPUINDPATH)\coredll.lib \
        $(_COMMONOAKROOT)\lib\$(_CPUINDPATH)\ceddk.lib \

我在SOURCES文件中的
TARGETLIBS 不加(1)编译出现连接错误
TARGETLIBS 加(1)编译出现NMAKE :  U1073: don't know how to make错误

引用 3 楼 andyhere2008 的回复:

加是肯定要加的，加了之后出现这个错误，说明没找到ceddk.lib
你试试看这个啊$(_COMMONOAKROOT)\lib\$(_CPUINDPATH)\ceddk.lib \

iaoun2001

我试过了下，结果是一样，但多出了两个WARNS
Macro: _COMMONPUBROOT not found in $(_COMMONPUBROOT)\sdk\lib\$(_CPUINDPATH)\coredll.lib $(_COMMONSDKROOT)\lib\$(_CPUINDPATH)\ceddk.lib.
Macro: _COMMONPUBROOT not found in \sdk\lib\ARMV4I\retail\coredll.lib $(_COMMONPUBROOT)\sdk\lib\$(_CPUINDPATH)\ceddk.lib.

NMAKE :  U1073: don't know how to make 'D:\WINCE500\PBWorkspaces\aaa\WINCE500\smdk2410_ARMV4I\cesysgen\sdk\lib\ARMV4I\retail\ceddk.lib'
NMAKE.EXE   -i -c BUILDMSG=Stop.  LINKONLY=1 NOPASS0=1 MAKEDLL=1 failed - rc = 2

我知道是怎么了，PB定制完wince后，没有将ceddk.lib复制到
$(_PROJECTROOT)\cesysgen\sdk\lib\$(_CPUINDPATH)\ceddk.lib\
下，我于是将ceddk.lib手动复制到以上目录就OK了。

总之，也谢谢两位的回复。
